Highly unlikely. If it is not physically damaged, and just chipped paint/ugly, Im with Bond-o on this one. Clean in up/sand it/strip it with paint stripper and repaint it. Put some elbow grease into it as a project and you will appreciate it that much more.
I bought a piece of that aluminum edge trim at my local West Marine just a few months ago. They had ordered it in for someone that never picked it up. Taco Metals still makes it. I am sure that is where West got it since they carry Taco rub rail. It was smooth instead of having the bead detail yours has.
